COM and TCP

Can anyone help me get started with a few lines of code that will help my app catch data inbound tcp data and route to an outbound com port?

I want the app to catch a "1" via tcp which the app will identify and send a corresponding string to a specified com port.

I think i've got the com portion down. I just need to know how to integrate the TCP portion. any pointers are appreciated.

Thanks

"COM" here means "Component Object Model" and not anything to do with serial ports.

Sorry.

Is this .net, vb6, etc?
Have you looked at the Winsock Control?

Use the Winsock control of vb. you can use it for both on server/client to send and receive data through ports.......
example: Private Sub Form_Load()
Winsock1.LocalPort = 1001
Winsock1.Listen
End Sub

Server Code :
Option Explicit
Private Sub Form_Load()
With Winsock1
.Protocol = sckTCPProtocol
.LocalPort = 2001
.Listen
End With
End Sub


Private Sub Winsock1_ConnectionRequest(ByVal requestID As Long)
Winsock1.Close
Winsock1.Accept requestID
End Sub

Private Sub Winsock1_DataArrival(ByVal bytesTotal As Long)
Dim pData As String
Call Winsock1.GetData(pData, vbString, bytesTotal)
Debug.Print pData
End Sub


Client Code :

Option Explicit

Private Sub cmdConnect_Click()
With Winsock2
.Protocol = sckTCPProtocol
.LocalPort = 0
.RemotePort = 2001
.RemoteHost = "localhost"
.Connect
End With
End Sub

Private Sub cmdSendData_Click()
Winsock2.SendData "Hi"
End Sub
